SI6606HT Transparent two-component self-healing silicone gel
SI6606HT Transparent two-component self-healing silicone gel
Product features and applications
GEL 6606HT is a transparent two-component self-healing silicone gel. After curing, it forms a special soft material that is buffered and automatically recovered. It is designed to insulate circuit boards from moisture and other harmful contaminants and to provide insulation against high voltages. Another use is to provide stress relief to protect circuits and interconnectors from high temperature and mechanical stress.
l 1:1 addition molding, strong viscosity
l High elongation; Excellent flexibility, eliminating mechanical stress
l Very low oil permeability after curing, excellent resistance to toxicity
l High temperature electrical insulation is excellent, to provide protection against high pressure
l Long-term use temperature range -50-220℃
l Excellent aging resistance and weather resistance
l Excellent waterproof, anticorrosive, moisture-proof, chemical medium resistance
l It can be used in semiconductor modules, sensors, etc
Typical applications
Power semiconductors, electronic sensors, MEMS Top Coating, automotive ECU integrated modules and other packaging protection IC chips, undersea fiber pooping and so on.

Operation Use craft
l Weigh the A and B components according to the ratio of 1:1, mix evenly, stand for
de bubbling or vacuum de bubbling, and then inject into the components (or modules) that need to be potting protection.
Matters needing attention
l The potting components can be put to rest
and cured at temperature (about 60 minutes under the condition of 80 ° C), or cured
directly at room temperature, about 24 hours.
l Vacuum defoaming of AB components after mixing can improve the performance of hardened products
l A and B components should be sealed and stored after use
l Too low temperature will lead to slow curing speed, it is recommended to heat curing
l GEL 6606HT will be difficult to harden in contact with materials containing sulfur, amine and tin
Storage and Transportation
l This product should be stored in A cool and period of A/B below 25℃ is 1 year.
dry environment below 25℃ , and the storage
l The products that exceed the storage period any abnormality before use.
should be tested to confirm whether there is
l These products are non-dangerous goods Be careful of leaks during transportation!
and can be transported as general chemicals.
